gamescope turns the laser into mouse clicks for apps Steam launches, so
dragging selected text. When Steam starts it, the launcher now runs Chromium
as a systemd user service outside Steam's process tree: its windows get their
own gamescope panel and real touches. Steam still tracks it and Stop closes it.
CHROMIUM_XR_STEAM_PANEL=1 keeps the old behaviour. --touch-events=enabled
because Xwayland labels its touch device as a pointer.
Before each start (when Chromium isn't running) the launcher also makes Allow
the default VR permission and drops per-site Blocks, so there's no
"Allow VR?" prompt.

Launched from the Steam library, Steam preloads gameoverlayrenderer.so,
which segfaults Chromium's zygote; the GPU process can't start and
Chromium quits after about 30 seconds. Found testing on a Steam Frame;
